PBINTING ATTACHMENT FOB GO'UNTERSKIVING MACHINES.

Application mea January 11, 1924. semi No. 685,554.

To all whom it may concern:

Be it known that I, FRED D. MALAGUTI, a citizen of the United States,residing at Somerville, in the county of Middlesex and State ofMassachusetts, have invented new and useful Im rovements in PrintingAttachments for gounterskiving Machines, of which the following is aspecification.

The object of the present invention is to v provide means in combinationwith a counter-skiving machine for rinting on the counter as it issuesfrom t e machine after being skived. It is not important what the wordsor symbols imprinted on the counter may be, whether they indicategrades, sizes, qualities, or the makers name, or what not.

The important fact is that, as the skived,

' counters are delivered from the machine,

the desired'symbols or words, or other de* vices are printed upon them.

A further important feature of the invention is that a ment is couplewith a part of the machine in-such manner that it is operated in aspecific way and for a certain purpose, only when counters are assedthrough the feeding rolls of the sklving machine, and does notoperatewhen the counters are not fed,

even though said rolls and the printing device of the printingattachment may be in operation. These specified parts which:

are thus connected for joint operation are, in the embodiment of theinvention here illustrated, the feeding pusher of the skiv-' machine,and the mk-distributing roller for the printing device. But within thescope of-the broad principles for which I seek protection, other partsof the mechanism may be similarly coupled and controlled one by theother.

The precise nature of the invention is more fully explained in thefollowing specification in connection with the detailed description ofone, form of machine embodying these principles, which machine isillustrated in the drawings provided herewith.

In such drawings,

Figure 1 is a front elevation of the ma chine referred to. v

Figure 2 is a plan view of the machine.

Figure 3 is a perspective view of the printing attachment.

Figure 4 is a vertical central section of the machine.

Figure 5 is a perspective view of the matrix roll, which is one of thepair of Cpart of the printing attachfeeding rolls for a counter blank,and con- In the drawin s, the numeral 10 represents the frame of a 8Wing machine, which may be of any desired construction. 11 represents amatrix roll having a matrix or recess 12, of the character and. for thepurpose known in the art. 13 represents a series of parallel diskscooperating with the matrix roll to feed the counter blank to astationary skiving knife 14. For the purposes of this description, thedisks 13 may be considered as collectively forming a feed rollcomplemental to the matrix roll. The matrix roll 11 is mounted on ashaft 15 and the disks 13 are similarly mounted on a shaft 16. These twoshafts are geared together by intermeshing gear wheels 17 and 18, andthe shaft 16 is driven by a gear 19 attached to it. Said gear receivespower from a pinion 20 on a shaft 201, on which also are the beltpulleys 21 and 22. Between the disks 13 are arranged presser fingers 23,supported pivotally on a rod 24, and having arms 25. These arms arepulled upon by springs 26 in a manner to press the fingers 23 toward,the matrix roll, so as to distort and offset the counter blank into thematrix cavity of the roll, leaving only the edge parts of ,the blank soprojecting as to be cut by the knife 14.

A magazlne for counter blanks to be skived is formed by a bracket orshelf27, on which are secured upright angle posts 28, to receive andposition the ends of the counter blanks. To these posts are 'securedcurved guards 29, which so far embrace the curved edges of the counterblanks near their ends as to retain the blanks in a pileon said shelf.The latter is attached to the side of the frame at about the level ofthe .tangent line beween the matrix roll and the complemental feed roll.

The guard or retaining means for the counter blanks, atthe end nexttothe rolls,

is cut away above the shelf27. for-a distance,

equal to the thickness of a single blank, or enough gfeater than suchthickness to permit the lank to pass through such space, but not enoughto admit two. blanks at the same time. p

A pusher 30 is arranged to slideover the surface of the shelf 27 frointhe outer part thereof toward the rolis, and it, has an edge shaped toconform with the outline of the counter blank, and in the plane of thelowermost blank, whereby it is adapted to en gage said blank and push itthrough the discharge opening 31 of the magazine to- Ward the rolls.This pusher has an arm 32 carrying a lug 33, to which is pivoted a link34. The link is also ivoted to an arm 35, fastened to a rock-sha t 36,on which it is also secured to a second arm 37, carrying a roll whichbears on the rim of the cam 38, on the shaft 16. A spring 381 engaged atone end with a fixedarm',.and at the opposite end with the arm 35,presses the roll of the arm 37 against the cam 38, so that the rotationof the cam reciprocates the pusher. Thus with each revolution of therolls, the blank pusher is given a back and forth reciprocation in timeto feed the lowermost blank of the pile to the shaft of the feed rolls,whenever the forward end of the matrix cavity is approaching the pointof tan-- gency with the lower feed disks.

As the blank passes between the matrix roll and feed disks, it isbrought against the edge of the lmife', and delivered above the knife,while the skivings fall upon .a deflector plate 39. From the knife thenewl skived counter as shown by dotted lines at 1 (Figure 4), passes toa printing device, which consists of a printing roll 40, and animpression roll 41. The printing roll has types on its face, as shown inFigure 3, and is mounted on a shaft 42, rotating in bearings 43, saidbearings being parts of brackets 44 and 44 which are secured to theframe of the skiving-machine. The impression roll in its turn, ismounted on a shaft 45, turning in bearings 46, which'are provided inparts of the skiving machine frame itself. These rolls, the printing andim' ession rolls, form a printing couple whic is an attachment to themachine. Not only are they the printing couple, but they also cooperateto grip and feed the counter, supplementing the action of the matrixroll and feedin disks, to draw the rear end of the counter past andawafrom the knife, after the counter has le the nip of the-matrix rolland disks. The impression roll 41 is driven for this purpose from theshaft 201, on

which the pinion 20 and pulleys 21 and 22 are also mounted, by a gear202 on said shaft, and a gear 203 on the shaft 45.

With this aspect of the machine in view, the matrix roll and disks maybe considered as the primary feeding means or couple of the combinedmachine and the printing couple may be considered as a secondary feedingmeans or couple, which combines the function of feeding with that ofprinting. For that purpose, the surface of the im ression roll ispreferably fluted or ribbe as shown'best in Figure 3. The types of theprinting roll in themselves, provide projections which cooperate withthe impression roll to grip the counter.

It is to be understood of course, that the printing roll may be of anydiameter and width of face, and may carry printing types of anydescriptiomto impress any desired words or symbols. on the counter,provided only that the area of the roll which carries the printingdevice is sufficiently within the outlines of the counter.

The ink or color for printing is contained in a fount 47, on an arm 48,which is secured detachably to a bracket 49, said bracket in turn beingdetachably secured to. one of the brackets 44 previously described.-

y slide on a rod 56, which is mounted at one end in the bracket 44.These arms 55, 55, are spaced apart by the shaft on which the rollerturns, and they are normallyheld in the position shown in Figure 3. Thearm 55 is pushed toward a collar 57 by a spring 58 confined between thearm 55 and the collar 59 on rod 56. i

The carrying roll 52 is also free to turn and move endwise on itssupporting rod 53, and is retained approximately in the position shownin Figure 3, by springs 60 and 60 which flank it and are confined bycollars 61 and 62, respectively.

The arm 55 of the distributing-roll holder is connected by a chain 63,with one arm g ing 67, which encloses the gears 17 and 18,

and is in turn attached tow the adjacent end member of theskiving-machine frame. The said lever has a second arm which isconnected by a chain 68, with a bell-crank lever 69, pivoted at 70 onthe shelf 27, which forms the bottom of the counter-blank magazine. Theother arm of this bell crank car ries a roll 71, which lies close to thesupporting surface of this shelf, and in position to be engaged anddisplaced by the curved edge of the counter b ank when the latter ispushed toward the primary feeding thus causing the ink which is eliveredin a narrow path to the roll 52, to be distributed fully over the facesof the printing de 'ce. By this action the counter blank, in ing fed tothe skivin machine, renders the printing couple e ective to print uponit when it has passed the skiving point and advanced to the printingpoint.

I claim:

-1. In a counter-skiving machine, the combination of a. knife; primaryfeeding mechanism in advance of the knife, includin rolls adapted togrip a counter blank, an means for rotatingthe rolls to feed the blankto the knife; and counter-feeding and printing mechanism beyond theknife, including rolls adapted to grip the skived blank, one being aprinting roll having types, and the other an impression roll, an meansfor driving the printing and impression rolls to cause the same tosimultaneously print and continue the feeding of the skived blank.

2. A counter-skiving machine comprising a matrix roll, a complem'entalfeeding roll, a magazine for'oounter blanks, means for feeding counterblanks successively from said ma azine to said rolls, a skiving knifepast WhlCh the blank is forced by the propelling action of said rolls, aprinting couple mounted as an attachment to said machine, and to whichthe counter sses its propelled progress from the s 'vin kmfe, and an inkdistributing roll for de 'vering ink to the printing member of saidcouple, and means controlled by the blank-feeding means of the skivingmachine for 'ving distrilllmting movements to said distributing ro a 3.The combination with a skiving machine, having complemental rollsadapted to grip and feed a blank to be skived, a knife arranged to skivethe blank so fed, and a preliminary feeder intermittentl acting todeliver counter blanks to said ro a printing attachment in which thecounter is delivered by said rolls after passing said knife, saidattachment including a normally inoperative element, and mechanismactuated by the preliminarg feederwhenevera counter blank is fed tereby, for making said element 0 erative in preparation for the arrivalo the blank so fed to the printing attaehment.

In testimony whereof I have aflixed my signature.

FRED D. MALAGUTI.
